Blade clamping tool

Abstract

The invention discloses a blade clamping tool and belongs to the field of processing tools. The blade clamping tool comprises a first shaping block, a second shaping block, a first pressing plate, a second pressing plate and a base, wherein the top of the first shaping block and the bottom of the first pressing plate are each provided with a first positioning groove, and the two first positioninggrooves define a first clamping space for clamping a first hinge pin of a blade; the top of the second shaping block and the bottom of the second pressing plate are each provided with a second positioning groove, and the two second positioning grooves define a second clamping space for clamping a second hinge pin of the blade; and a matching face is arranged on the side face, facing the second shaping block, of the first shaping block, and used for abutting against a to-be-processed working profile of the blade. The blade can be quickly, accurately and firmly clamped through accurate cooperation of the two pairs of positioning grooves, and the requirement for blade batch processing can be met.

Description

technical field [0001] The invention belongs to the field of processing tooling, in particular to a blade clamping tooling. Background technique [0002] The blade is an important part of the gas turbine, which mainly includes a working surface and pins fixed at both ends of the working surface. [0003] When machining blades, two pin shafts are usually processed at both ends of the blade blank first, and then the working surface is processed. [0004] However, since the blade blank is an irregular structural part, when using an ordinary 3-axis vertical machining machine to process the blade blank, it is impossible to quickly and accurately clamp the blade blank, and it needs to be repeated many times during the processing Adjust the clamping of the blade blank, resulting in low processing efficiency. However, if a multi-axis machine tool is used for processing, although the problem of repeatedly adjusting the clamping of the blade blank can be avoided, since the multi-axi...

Problems solved by technology

[0004] However, since the blade blank is an irregular structural part, when using an ordinary 3-axis vertical machining machine to process the blade blank, it is impossible to quickly and accurately clamp the blade blank, and it needs to be repeated many times during the processing Adjust the clamping of the blade blank, resulting in low processing efficiency

However, if a multi-axis machine tool is used for processing, although the problem of repeatedly adjusting the blank clamping of the blade can be avoided, because the multi-axis machine tool is relatively expensive, it will lead to an increase in the processing cost of the blade, which is not conducive to the control of the processing cost.
